Yeast Glucose Chloramphenicol Agar (YGC)
Selective Medium for Yeast & Mold Isolation
Catalog No: AS-1381 Dehydrated Powder Prepared Medium: Pale Amber Agar HS Code: 3821.00
Selective Medium for Reliable Recovery of Yeasts and Molds
Yeast Glucose Chloramphenicol Agar (YGC) is a selective culture medium designed for the isolation, cultivation, and enumeration of yeasts and molds from food, beverage, pharmaceutical, cosmetic, water, and environmental samples.
The elevated glucose content supports fungal growth, while chloramphenicol suppresses bacterial contamination, enabling clearer recovery and more accurate fungal counts in routine quality-control and environmental monitoring workflows.
Why labs use it
- Selective inhibition of bacteria by chloramphenicol
- Supports broad growth of yeasts and filamentous fungi
- Clear colony development for enumeration
- Reliable for routine QC and compliance testing
Typical applications
- Yeast and mold enumeration in food and beverages
- Pharmaceutical and cosmetic microbial limit testing
- Environmental and water microbiology
- Air and surface fungal monitoring
